Aluminum foil lunch boxes are usually used as paper-wrapped beverage packaging. The thickness of the aluminum foil in the packaging bag is only 6.5 microns. This thin aluminum layer can be waterproof, preserve umami, anti-bacterial and anti-fouling. The characteristics of preservation of fragrance and freshness make the aluminum foil lunch box possess the properties of food packaging, and the characteristics of high temperature resistance and oil resistance make it easy to control all kinds of hot meals, even in the face of the old difficulty of takeaway packaging-oil and soup There are more Chinese food, not to mention, it can be said that aluminum foil lunch boxes have natural take-out attributes.
The people regard food as the heaven, and food as the first priority. The manifestation of food safety not only exists in the food itself, but also includes the lunch boxes in contact with the food.

If the concentration of this harmful substance exceeds the standard, the poisoning will be even greater. The main material of the aluminum foil lunch box is aluminum foil. The surface of the aluminum foil has a dense oxide layer. The chemical properties of this oxide layer are relatively very stable. As long as it is not in a strong acid environment, aluminum ions will not be precipitated.

Compared with the geological changes caused by “white pollution”, aluminum lunch boxes can be weathered after being placed in the soil for two to three years, and will not cause continuous damage to the land and implanted nature changes.
Aluminum has a physical property, that is, ductility. Compared with other metals, aluminum of the same quality can be used to process a larger surface area and pack more things.
